Hello,
We are trying to use ov2680 camera module with sc20 som.
but camera is not detecting,
We have configured driver but it gives below error,
i2c-msm-v2 78b7000.i2c: NACK: slave not responding, ensure its powered: msgs(n:2 cur:0 tx) bc(rx:2 tx:2) mode:FIFO slv_addr:0x36 MSTR_STS:0x091343c8 OPER:0x00000010

[ 21.230533] ov2680 power up failed
after trying to find out the solution,
We get to know that this is because of power sequence
can you please confirm if power sequence is correct or not
static struct msm_sensor_power_setting power_setting[] = {
{
.seq_type = SENSOR_VREG,
.seq_val = CAM_VIO,
.config_val = 0,
.delay = 0,
},
{
.seq_type = SENSOR_VREG,
.seq_val = CAM_VANA,
.config_val = 0,
.delay = 0,
},
{
.seq_type = SENSOR_VREG,
.seq_val = CAM_VIO,
.config_val = 1,
.delay = 1,
},
{
.seq_type = SENSOR_VREG,
.seq_val = CAM_VANA,
.config_val = 1,
.delay = 4,
},
{
.seq_type = SENSOR_GPIO,
.seq_val = SENSOR_GPIO_STANDBY,
.config_val = GPIO_OUT_LOW,
.delay = 0,
},
{
.seq_type = SENSOR_GPIO,
.seq_val = SENSOR_GPIO_STANDBY,
.config_val = GPIO_OUT_HIGH,
.delay = 7,
},
/{

.config_val = GPIO_OUT_LOW,
.delay = 1,
},
{
.seq_type = SENSOR_GPIO,
.seq_val = SENSOR_GPIO_RESET,
.config_val = GPIO_OUT_HIGH,
.delay = 1,
},/
{
.seq_type = SENSOR_CLK,
.seq_val = SENSOR_CAM_MCLK,
.config_val = 24000000,
.delay = 10,
},
{
.seq_type = SENSOR_I2C_MUX,
.seq_val = 0,
.config_val = 0,
.delay = 0,
},
};
I am attaching datasheet link of ov2680 here please confirm power sequence again

Thanks in advance, I hope issue will get resolve ASAP.
